• one or more characters follow the "R" character (using the "*" Wildcard character).
If you include only the Wildcard in the Pass Fail Match Code, all decoded strings are matched.
Composite Codes
If the Composite Code input property is True, the tool decodes two different code types:
• The first code is one of these 1D codes: GS1 128, Code 128, GS1 Databar, GS1 Databar Stacked, GS1
Databar Limited, GS1 Databar Expanded, or GS1 Databar Expanded Stacked.
• The second code is a 1D MicroPDF code.
If the Composite Code input property is False, only the linear code in the Composite code is decoded and its
type is indicated. MicroPDF is a stacked code but is still considered linear
When the two 1D codes are linked by the composite rule, the output "Code Type Found" is set according to
the following table:

In the Readers Drawer
The OCR tool reads character strings to find matches with trained characters (Optical Character Recogni-
tion) and verifies those strings. Characters are read by finding the best matching character from a trained
library or string, within a minimum match score. If the tool finds no matching character, it uses a substitution
character to indicate it.
